IPC: H01S5/223
Filed: 1983-10-14
Abstract: PURPOSE:To prevent leakage current of the photo absorption layers due to an optically pumped minority carrier by a method wherein layers, which perform photo absorption, and layers, which perform current constriction, are separated from each other. CONSTITUTION:An n type semiconductor layer 2; a semiconductor layer 3 having a smaller forbidden band width than that of the layer 2; a p type semiconductor layer 4 having a larger forbidden band width than that of the layer 3; semiconductor layers 8-10, each having a striped groove; and a p type semiconductor layer 6 having a larger forbidden band width than that of the layer 3 are provided on an n type substrate 1. The layer 8 is a p type layer and has a smaller forbidden band width than that of the layer 3. The layer 9 has a p type and the layer 10 has an n type. The layers 9 and 10 have a larger forbidden band width than that of the layer 3. The layer 3 and the layer 8 substantially absorb respectively lights, which are emitted from the laser active layers and the active layers, and both make a control of transverse mode performance. As a result, leakage currnent of the photo absorption layers can be prevented by a p-n junction, which is formed by the layers 9 and 10.

Inventor: KATOU HIROMASA
IPC: G08G1/017
Filed: 1994-07-20
Abstract: PURPOSE:To prevent a communication error owing to an interference of carrier waves having the same frequency in a moving body discriminating system furnishing plural interrogators. CONSTITUTION:Interrogators X1, X2, X3... are provided in respective lanes. An oscillator 10 common to all the interrogators X1... is provided, its standard signal S6 is input to the PLL circuits of the interrogators, it is divided at a set specific ratio, and a carrier wave S7 at a specific frequency f1 is formed. The amplitude of the carrier wave S7 is diverted and modulated (ASK) in a time period A, while a nonmodulated carrier wave of the frequency f1 is output in a time period B, and a responder modulates this carrier wave, and returns it. On the other hand, in the interrogator X3, the perfectly the same frequency of carrier wave in the interrogator X1 is used through the PLLs, and the transmitting conditions in the time periods A and B are the same as in the interrogator X1. Since the carrier wave frequencies are coincident perfectly, a beat communication error owing to the mixture of the carrier waves in the interrogator X1 and in the interrogator X3 is never generated.

Title: Optomagnetic storage device
Inventor: DEGUCHI TOSHIHISA
IPC: G11B7/12
Filed: 1982-10-29
Abstract: PURPOSE:To prevent storage capacity from reduction due to the arrangement of a track address signal recording part by arranging two kinds of photo-detectors supplying magnetized information signals in reverse phase each other to a magneto optic head reading out recording information from a recording medium. CONSTITUTION:The magnetized information signals obtained from the photo- detectors 26, 27 for detecting memory information signals which are arranged on the reflection sides of respective polarized beam splitters 21, 22 have reverse phases each other. When an optical beam spot scans the track address signal recording part 3, the quantity of reflected light is changed in accordance with the existence of an already set-up pit. Since the changing signal is changed independently of the change of a degree of polarization the memory information signal detecting photodetectors 26, 27 detect signal change in the same phase each other. Therefore, a track address signal can be obtained by subtracting the detected signals of the memory information signal detecting photodetectors 26, 27 each other and adding the magnetized information signals without the influence of the track address signal.

If so, the secondary information on the data is read out the RAM 4 and listed up on a display 6. Then a fact whether the data is final or not. If not, the data number is increased so that the next data is defined as the final one. Thus the list-up frequency is reduced for the data on the archival time limit and the file control is simplified.

Abstract: PURPOSE:To prevent the generation of a backfire explosion accident caused by gas leakage, by a method wherein a pressure detector is provided between two opening and closing valves of a combustion gas introducing pipeline and an ignition switch is made inoperative when detected pressure reaches a set value or less. CONSTITUTION:Opening and closing valves V1, V2 operated in definite delay time difference are provided to the inlet and the outlet of the combustion gas introducing pipe of an arranged pipe part A and a pressure detector 4 for detecting the pressure of gas to be introduced is connected between said values V1, V2. When a power switch S1 is turned ON, the valve V1 is opened but the valve V2 remains as it is closed. When gas pressure detected during this time by the detector 4 is lower than a set value, a stand-by switch S3 is held under an OFF-state. Therefore, even if an ignition switch S2 is turned ON, the valve V2 is not opened while the combustion gas is not supplied to a burner 3 and, therefore, a backfire explosion accident caused by gas leakage can be prevented.
